FODDER-SHREDDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 596,013, dated December 21, 1897.

Application filed May 12, 1897. Serial No. 636,214. (No model.)

To all whom it may concern.-

Be it known that I, JOHN OARREY, a citizen of the United States, residing at De Soto, in the county of Jefferson and State of Missouri, have invented certain new and useful Improvements in Fodder-Shredding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention, as will be hereinafter fully described and claimed, and illustrated in the accompanying drawings,has relation to shredding or threshing machines, and more partioularly to machines of the character speciwhich will separate the grain in a cleanly condition and at the same time thoroughly shred or tear the blades and stalks into minute particles and convey the same as partof the operation to the desired storage -chamber therefor, and also to elevate the grain thus separated to any preferred location. By thus reducing the'stalks and blades to a semipulverized condition a valuable food is produced from otherwise unavailable substances.

A further object in carrying out my invention is to produce a mechanism of the most simple character possible consistent with the character of the work which it is designed to perform.

In the accompanying drawings, Figure 1 is a side elevation showing the general or outward appearance of my invention as applied to use. Fig. 2 is a detail side elevation of the shredding-cylinder and the teeth thereon. Fig. 3 is a detail of one form of fan which may be employed. Fig. 4 is a cross-section of the shredding-bar with which the teeth on the cylinder cooperate. Fig. 5 is a longitudinal central section of the machine, showing a transverse section of the feedingrolls and shredding-cylinder, also showing fan in elevation. Fig. 6 is a perspective detail of the shredding-bar. Fig. 7 is a front elevation of the feeding-rolls, showing part of the teeth on the shredding-cylinder in the background and also showing an edge view of the fan, the casing thereof in section. Fig. 8 is a de: tail of the clutch.

In referring to the various details of my invention I will confine my description to the preferred construction, though the equivalent is comprehended by me. The details will be designated by figures, the same figure applying to the same part throughout the views.

Briefly stated, my invention consists in providing feeding-rolls which will positively draw in the fodder or other substance to be treated and hold it upon a shredding-bar for the cooperation of the teeth of the cylinder, the travel of the substance treated being so regulated with reference to the rotation of the shredding-cylinder that such substance will be severed and shattered into very small pieces, rendering it possible to utilize every particle thereof as food for stock, thus producing a valuable article of commerce from subject-matter otherwise lost if not so treated,

and, further, in removing the corn from the stalk free from dirt, &c., by means of said feeding-rolls and incidentally cleaning the grain and directing the shredded fodder into a receptacle provided therefor, thus enabling me to utilize one fan to create suction an driving-blast.

In carrying out my invention I provide a housing or framework of any preferred shape, though that illustrated in Fig. 1 is,it is thought, amplysufficient to meet the requirements, in which 1 represents the base-frame, while 2 and 3 are vertical standards erected thereon, the latter preferably extending slightly above the body of the machine for the purpose herein set forth. Standards 2 and 3 are connected at a point on a line with the upper end of the former by the horizontal frame 4, properly secured to said standards. Said framework thus provided is properly inclosed by siding 5 to provide a housing for the interior parts. In the upper part of the frame I mount in suitable bearings connected to the standard 3 the horizontally-disposed feeding-rolls 6 and 7, the former being above the latter and in close mesh therewith,-though their relation to each other may be easily controlled by providing adjustable bearings. Said rolls may consist of true cylinders, though I prefer to form them to have the outline of truncated cones, the large end of one being in engagement with the small end of the other, thus compensating for the varying diameters thereof and leaving the lower edge of the lower roll and the upper edge of the upper roll in planes which are substantially parallel with each other.

I prefer to somewhat roughen or corrugate the peripheral faces of both rolls substantially as shown in Figs. 5 and 7, though any preferred plan may be employed to provide frictional faces, the object being to enable them to grasp the fodder or substance treated and more reliably draw it into engagement with the shredding-eylinder 8, which is suitably mounted upon said framework, substantially as shown in Fig. 5. The body of said cylinder is provided with a series of rows of teeth 9. I prefer to incline all of the teeth in one row laterally, while the teeth in the suceeeding row are inclined in an opposite direction, each alternate row being disposed in a different direction, the object being to present a shearing or cutting edge 10 for close engagement with the bars 11 and 12, preferably integrally formed upon the supporting wall or bracket 13. The shredding-bar 11 extends toward the lowerfeeding-roll and approaches closely in the path thereof and is preferably slightly depressed as it approaches said roll,

the object being to present a slight incline for the fodder as it is forced toward the free edge of the bar 11, ready for engagement with the series of teeth upon the cylinder.

By giving a different inclination to each alternate row of teeth it follows that any tendency of the fodder to move laterally out of engagement with the teeth and go between them instead of being sheared off thereby or to wind around the cylinder between the teeth is corrected by the inclination given to the succeeding row of teeth, thus tending to hold the matter treated until the shredding process is thoroughly completed.

The bracket 13 has the body part in the form of an arc of a circle, by which it better codpcrates with the shredding-cylinder and is provided at either end with lugs or anchoringpoints 14, designed to take into the contiguous part of the frame, as in apertures provided in the standard 3, which arrangement will reliably hell it in position.

In Fig. 6 it will be observed that the shredding-bar 11 and its extension toward the feeding-roll is triangular in general outline, the object in thus providing the tapered end 11 being to compensate for the tapered form of the feed-roll and enable it to be closely approached by said bar throughout its length, thus preventing the substance treated from dropping between it and the lower roll.

The position of the cutting edges of the shredding-bars 11 and 12 is such that they will lie in the are of the circle described by the ends of the teeth, thus providing two bars for cooperating with said teeth and thus insuring a more thorough performance of the disintegrating process.

\Vhile the required power for operating my improved shredding-machine may be applied in any preferred way, I prefer to apply such power direct to the shredding-cylinder, one of the journals 15 of which is extended sufficiently beyond the frame to provide for the -mounting of the driving-pulley 16, to which suitable belting from the engine or other source of power may be attached. I also 10- cate upon the shaft 15 the fly-wheel 17 to give the requisite amount of momentum to the cylinder and enable it to reliably perform its work. Upon the opposite end of the cylinder I extend the journal 18 thereof sufliciently beyond the frame to provide for the mounting of a friction-clutch, consisting of the gear 19, having an outwardlytapered bore designed to receive the conical face of the fixed wheel or clutch 20, properly keyed to said journal.

It will be seen that the con is integrally formed with the sleeve 21, which provides an additional means for more reliably securing these parts to the shaft. Disposed around said sleeve is the spring 22, the inner end of which is designed to bear against the outer face of the gear 19 and thereby normally hold it into frictional contact with the cone 20 and cause it to rotate therewith.

In order to provide for the regulation of the tension of the spring 22, I prefer to thread the outer end 23 of said sleeve and seat thereon the eontrolling-n ut 24, by means of which said spring may be brought to bear lightly or firmly against the gear 19.

Upon the outer end of the journal 18 I firmly secure the baud-wheel 25, designed to 006p erate with the baud-wheel 26 upon the shaft 27, upon the inner end of which the fan 28 is mounted. The gear 19 is in mesh with the gear 29, which is firmly secured to the end of the journal 30 of the lower feeding-roll.

To the journal 31, upon the opposite end of the lower feeding-roll, I key the gear 32, designed to mesh with the gear 33, properly mounted upon the shaft 34 of the upper feedin g'roll, and bysu ch arrangement of the parts I first communicate power to the shreddingcylinder and thence to the feeding-rolls.

If at any time it is desired to immediately stop the rotation of the feeding-rolls, I am enabled to do so by means of the friction-clutch just described, as a simple inward movement of the operating-lever 35,pivoted to the standard 3, will cause the gear 19 to move against the tension of the spring 22 and thus prevent further rotation of the gear 30, preventing further rotation of the roll. By simply releasing the lever the action of the spring 23 will force the gear 19 into engagement with the cone 20 and thus cause the feeding rolls to be actuated.

By reference to Fig. 7 it will be observed that I provide an inclined chute for conveying the grain downward to one side of the machine, as the floor is indicated by sectionlines 36, thus bringing the corn in the path of the suction caused by the fan 28. Suitable means may be provided, as by an endless carrier 4:1, for conveying the corn thus deposited to any desired point, said carrier being actuated by proper connections with the other parts;

I prefer to mount the fan 28 in one side of the frame and provide the outward extension or housing 37 and communicating with said housing is the upwardly-directed conveying tube or chute 38. Proper connection may be made with the delivery chute or section 38, as by sections 39 andAO, in order to provide means for conveying the shredded fodder in any point where it is desired to deposit it. The chute thus provided may be suitably connected to the upwardly-extended end of the standard 3, as by rope ll, designed to be wound upon a suitable Windlass mounted in said standards, enabling the chute formed of as many sections as may be required to be easily raised or lowered by means of said Windlass.

By the arrangement of the parts just described it will be seen that as the fodder is fed into the feeding-rolls the grain thereon Will be stripped from the stalks and from the husks surrounding them and will fall upon the inclined fioor 36 and thence by gravity to the lower end of the chute thus provided, being removed by an endless carrier, or manually, if preferred.

By locating and constructing the fan as herein illustrated I am enabled to produce a violent suction, which will draw through the fan all of the shredded fodder, dust, &c;, and leave the corn in a cleanly condition. After the shredded fodder, &o., has passed the fan it will be forced by the blast thus induced into the delivery-ch ute 38 and thence to the desired point prepared for its reception, thus enabling me to perform the two operations of cleaning the grain and directing the shredded fodder with a single fan, that being the essential feature and valuable result of my invention.

By properly constructing the delivering or end section of the chute and moving the same from side to side during the process of deliv: ery much labor may be dispensed with, as the shredded material may be deposited directly by the machine at the place prepared for its storage.

By constructing and mounting the shredding-bars substantially in the manner described I am enabled to dispense with what are usually termed concaves and teeth therefor, as said bars will so coiiperate with the inclined teeth upon the cylinder that a shearing or cutting process is set up, rendering it possible to more thoroughly disintegrate the matter treated without clogging or choking the parts. I

By providing the friction-clutch, as herein described, it is possible to instantly stop further rotation of the feeding-rolls when it is found necessary to do so in order to prevent any foreign substance that may be found in the material treated from entering the machine and to lessen the liability of the party feeding the machine to accident.

WVhile it is thought that best results will follow the disposition herein shown for the teeth, yet it will be understood that they may be spirally disposed upon the cylinder, thus enabling them to successively codperate with the shredding-bars, resulting in a less violent jar or strain upon the parts.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1'. In a fodder-shreddin g machine, the combination of a rotatable cylinder having rows of teeth alternately inclined, with a bracket formed like an arc of a circle and carrying shredding-bars on its top and bottom, the top bar extending rearward to receive the fodder as set forth.

2. In a fodder-shredding machine, a rotatable cylinder having rows of teeth, feedingrollers to convey the fodder, a bracket located between the feeding and shredding devices, formed like an arc of a circle and having shredding-bars on its top and bottom, the upper bar extending rearwardly between the feeding-rollers, all combined as set forth.

3. In a fodder-shredding machine, a rotatable cylinder having rows of teeth, a bracket formed like an arc of a circle, having cuttingbars on its lower and upper edges, the upper bar being triangular in form and having a rearward extension to feeding-bars, said feeding-bars, and means to operate these parts, all combined as set forth.

4. In a shredding-machine, the combination with a suitable housing of a pair offeeding-rolls, shredding-bars mounted on the delivery side of said rolls, a shredding-cylinder having a series of teeth cooperating with said bars, and a friction-clutch consisting of a cone and sleeve rigidly mounted on the drivingshaft therefor and means to throw the clutch into and out of operative condition, as set forth.
